Specification of Letters Patent.

Patented July 16, 1907.

Application filed October 17, 1906. Serial No. 339,316.

Phonographs, of which the following is a specification. Y

This invention relates to starting and stopping mechanisins ior phonographs. v

It has for an object to provide a means connected to the starting lever and operated automatically either by the closing and the opening oi the gate or by the shifting of the locklior the gate.

Other and further objects will appear in the following description and will be more particularly pointed out in the appended claims.

In the drawings :-Figure 1 is a front elevation of one embodiment of our invention, and Fig. 2 is a front elevation of another embodiment o our invention.

vIn the embodiment shown in Fig. l, 1 indicates the record cylinder, 2 the cylinder frame, 3 the bed plate, 4 the pivoted starting lever, 5 the .,motor shaft, 5 the motor,- 6 the brake disk and 7 thehinged gate, all o which are of any desired construction.

Positioned below theront end of the gate 7 when the gate is in closed position, is the upper beveled end 8 of a vertically movable plunger or trip 9 which works through an opening inthe bed plate and is pivoted at its lower end to one arm of a b ell crank lever l0 suspended from the underside of the bed plate by a hangerv 11. 'lhe other arm oi the bell crank lever is pivotall connected to a link 12 which in turn is pivotally con-- nected to the starting lever 4. It is apparent that when the gate is closedV it will'ride on the upper bevelcd end of the plunger 9 and depress the same, which in turn, through the bell crank lever 10 and link l2, will shift the starting lever and release the motor shaft. When the gate is opened to remove the cylinder, the plunger will rise under the action of a. coil spring 13 interposed `b etween the bed plate and the headed and beveled upper end 8 of the plunger 9, thus shifting the starting lever to stop the me tor shaft. A

In the embodiment shown in Fig. 2, the known construction of the machine may b e lthe same except that the gate is held closed by a manually operated cam lock 14 which is also old in the art. To this manually plunger 9L which extends through an opening'in the bed plate and is swiveled to one end of a bell crank lever 10 hung from the under side of the bed plate by a hanger l1. A link 12 connects the startinglevcr 4 and the bell crank lever 10, The starting and the stopping is in this latter embodiment positively controlled by the gate lock. i

Itwill be noted that all parts of our invention, with lthe exception of the upper, end oi the plunger 9 or 9,

are mounted belowl the bed plate and are thus out of the way of the operator. 1 In both embodiments, a part of the gate either the gate body or the gate lock controls the plunger and consequently the starting lever, both on opening and on closing'the gate.

Having thus described our invention, what we claim and desire to secure by Letters Patents, is

1. In a starting and stopping mechanism for: phonographs, the combination with the starting lever, a gate part, a motor shaft, a brake disk upon'tlieshaft; of a plunger' controlled by the gate part, a bell-crank lever connected to the plunger, and a link connecting the bellcrnnk. 4and the starting lever to operatethe latter with respect to the brake disk upon opening or closing of the gate.

2. In a startingnnd stopping mechanism for phonograplis, the combination with the bed plate, the starting lever und a gate part, of means connected to the starting lever below the bed plate :1nd controlled by the gate part.

3. In n. starting and stopping mechanism for phonographs, the combination with the bed plate, the starting lever and the gate part, of a spring actuated plunger operated by the gaie part, a bell crank lever hung from the under side ot the bed plate and connected to the plunger, and a link connecting the bell-crank lever and the starting lever. y r

4. In a starting and stopping mechanism for phono graphs, the combination with the starting lever, 'and a gate part, of a plunger controlled by the gate part.' a bell crank lever connected to the plunger, and a link connecting the bell' crank lever and the startnglever.

5,. in a phonograph, .a motor for operating the phonograph, a gute for the phonograph cyllnder,means connecting the said gate with the motor, whereby the motor is started and stopped by operating the gate. Y

-In testimony whereof we have signedour names to this specification in the presence of two subscribing witnesses.
